let Edna and their children attend a church and accuses Edna of indoctrinating their children. Betty hands God Hilliard the Bible, and he slaps her in retaliation. The incident causes God Hilliard's family to escape from him, and Hilliard enters a period of emotional crisis. His followers discover him crying on his desk. He apologizes to the followers and is left alone, as he strikes a piano note. God Hilliard then voices a challenge to God Almighty; if he is 'mightier than man', he will 'give up everything' for God Almighty. At a church, God Hilliard attends in disguise, but waits until every attendant has left the church. He then steals a piece of sacramental bread from the church. At his house, God Hilliard uncovers his stolen item and wonders what happens if the bread can or cannot bleed. God Hilliard proceeds to pierce the bread, but he joyfully discovers that the bread does not bleed. He then returns to the Eternal Man's Party building. A slime trail appears, which God Hilliard follows. While on the run, God Hilliard comes back to his house and slowly walks to his room. Affected by God Almighty's power, as he enters his room, God Hilliard is therefore defeated in a challenge.
